Anticausative Alternation
C

Description

The original agent is completely eliminated. An object (direct or indirect) is now the subject and the verb gets reflexive. (In the 'true' reflexive alternation, the change from object to subject does not take place.)Ex. Ich oeffne den Vorhang --> Der Vorhang oeffnet sich. (Middle alternation in English) There may be more examples on another level (Die Kartoffeln schaelen sich gut.) but normally one uses lassen (Die Kartoffeln lassen sich gut schaelen.)
